Near-complete torque teno virus (TTV) genome identified in a blood donor infected with hepatitis B virus (HBV).

Abstract

We have identified a near full-length torque teno virus (TTV) genome sequence in plasma from a blood donor infected with hepatitis B virus. The consensus sequence of TTV was extracted from Nanopore metagenomic sequencing. The identified TTV open reading frame 1 is 3,062 nucleotides (nt) long and shares 90%-100% identity with other human TTVs.
